for using three different sets to cover all makes of saws; and toprovide simple and convenient means for adjusting the device.

I attain the objects of my invention by the mechanism illustrated in theaccompanyin drawings, in which Figure 1 is a side elevation of theinvention, with a portion broken away to show opening 15 Fig. 2 is aview of the invention, partly in section and partly in elevation, theportion in section being a section on the line 22 of Fig. 3; v

Fig. 3 is a rear elevation; and

Fig. 4 is a transverse section on the line 44 of Fig. 1.

Like numerals designate like parts in each of the views.

Referring to the accompanying drawings, I provide a suitable handle 1terminating in a bottom jaw 52, on which is adjustably mounted a movableanvil plate 13, adapted to be set forward or back by means of screws 14which extend through oblong openings 15, the heads of the screws beingwider than said openings, as indicated in Fig. 3. I further provide anadjusting screw 16 and a suitable washer 17 for raising or lowering thesetting block or anvil plate 13. I further provide a setting pin 8mounted at the angle shown in the accompanying drawings in the extensionor head 3, and normally held in retracted position by a suitable spring11. I further provide a suitable cotter pin 10 mounted in setting pin 8,and adapted to seat in slot 12 in head 3 when setting pin 8 is inretracted position, as shown in Fig. 2. Setting pin 8 is provided with arounded end 9. Setting block 13 is rovided with a rounded portion 18 asillustrated in the drawings. I provide a sight opening 5 through whichthe rounded end of setting pin 8 may be viewed when the device is inoperation. 19 designates the front surfaces ISp'ecification of LettersPatent.

of the members 20 which connect head swith handle 1. Pin 8 is slidablein passage 6 in head 3; and is provided with a suitable head 7 againstwhich spring 11 presses. I provide a suitable overhanging lip 4 on head3, as illustrated.

v In use the device is operated by placing the set over the saw toothand pushing or holding against the saw while striking the setting pinwith a light hammer. The

rounded end of the setting pin will strike all teeth of the saw inexactly the same place and will positively set every tooth alike withoutusing a spider or rectifying gage of any kind. By providing the meansfor adjusting the setting block or anvil plate illustrated, that membermay be adjusted to suit the instrument todifferent kinds of saws orwhere it is desired to give more or less set to the teeth of the saw. Byloosening the side screws 14 the setting block 13 may be moved downward,the screw 16 first being loosened and the device adjusted to any gage orset desired, the side screws 14 then being tightened, and the settingblock being held in the desired position by the gage screw 16 or itswasher 17. When once adjustedthe device will set the saw perfectlyaccording to the gage to which it 'is adjusted; for example, it willrequire a smaller set for a hand saw, buck saw or small band saw, andone of larger size for sawmill band saw. It is within the contemplationof my invention to provide different sets to cover all makes of saws.

What I claim is: i

1. In a device of the class described, the

means for longitudinally adjusting and setting said block, and means forholding said block in its longitudinally adjusted position in thehandle, whereby the device is adapted for setting the teeth of differenttypes of saws.

2.'In a device of the class described, the combination of a handlehaving an extension head, arms connecting the handle with said head andhaving a slght openlng posiverse small pin mounted in the settingpinadapted to limit its retracted movement, a

setting block having a rounded portion and means for setting andadjusting said block,

10 said means comprising a bottom jaw having beyond the block, and agage screw and washer engaging the forward edge of the setting block andadjustably securing same in the V desired adjusted position, wherebythe: de vice is adapted for setting the teeth of dif-' ferent types ofsaws.
